From the album Return comes the Pony Up T shirt. We think this design about sums it up! Hebrews says:

“My son, do not regard lightly the discipline of the Lord,
Nor faint when you are reproved by Him;
For those whom the Lord loves He disciplines,
And He scourges every son whom He receives.”

“Therefore, strengthen the hands that are weak and the knees that are feeble, and make straight paths for your feet, so that the limb which is lame may not be put out of joint, but rather be healed.”
